xml rpc

This section describes how the xml-rpc can be used for remote method invocation.  The xml-rpc java library can be obtained from Apache (http://ws.apache.org/xmlrpc/)

xml-rpc method invocation

public Vector execute(UserProfile user, String methodName) throws XmlRpcException, IOException

{

Vector constants = null

Hashtable constant = null;

Vector params = new Vector(1);

XmlRpcClient xmlrpc = new XmlRpcClient(user.getUrl()+

EclipseJIRAConstants.XMLRPC_URL);

String loginToken = login(user);

params.add(loginToken);

constants = (Vector)xmlrpc.execute (EclipseJIRAConstants.JIRA_PREFIX+methodName, params);

logout(user, loginToken);

return constants;

}

 

private String login(UserProfile user)throws
XmlRpcException, IOException

{

XmlRpcClient xmlrpc = null;

Vector params = new Vector(2);

String loginToken = null;

 

xmlrpc = new XmlRpcClient (user.getUrl()+

EclipseJIRAConstants.XMLRPC_URL);

params.add(user.getUserID()); // userid

params.add(user.getPassword()); // password

// this method returns a string

loginToken = (String)xmlrpc.execute(EclipseJIRAConstants.JIRA_PREFIX+

EclipseJIRAConstants.LOGIN_METHOD , params);

returnloginToken;

}

 

private void logout(UserProfile user, String loginToken)
throws

XmlRpcException, IOException

{

XmlRpcClient xmlrpc = null;

Vector params = new Vector(1);

xmlrpc = new XmlRpcClient (user.getUrl()+

EclipseJIRAConstants.XMLRPC_URL);

params.add(loginToken); // token

// this method returns a string

xmlrpc.execute(EclipseJIRAConstants.JIRA_PREFIX+ EclipseJIRAConstants.LOGOUT_METHOD, params);

}

 

This section describes how to process RSS Feed using Java

Step 1: First get the RSS feed by reading the appropriate URL

public String sendURL(String location) throwsIOException

{

URL url;

StringBuffer stringBuf = new StringBuffer();

url =new URL(location);

BufferedReader in = new BufferedReader( new InputStreamReader( url.openStream(),"UTF-8"));

String inputLine;

boolean foundRSS = false;

boolean isRSSEnd = false;

while((inputLine = in.readLine()) != null)

{

if(inputLine.matches(".*<rss.*"))

{

foundRSS = true;

}

if(foundRSS)

{

inputLine = unicodeToStr(inputLine);

inputLine = replaceHTMLEncoding(inputLine);

stringBuf.append(inputLine);

// System.out.println(inputLine);

if(inputLine.matches(".*</rss>.*"))

{

isRSSEnd = true

}

}

if (isRSSEnd)

{

break;

}

}

in.close();

}

Step 2: Use the RSSDigester Class (provided by Apache, http://jakarta.apache.org/commons/digester/)to parse the RSS feed.

RSSDigester rssDigester = null;

String rssString = null;

Channel rssChannel = null;

Item[] issues = null;

StringReader stringReader = null;

rssString = sendURL(location);

rssDigester = new RSSDigester();

addItemProperties(rssDigester);

stringReader = new StringReader(rssString);

rssChannel = (Channel)rssDigester.parse(stringReader);

stringReader.close();

issues = rssChannel.getItems();

Step 3: If the item in the RSS is different from what is supported by RSSDigester, Define your own Item class

 

public class IssueItem extends Item {

protectedString environment;

protected String key;

protected String keyID;

protected String summary;

protected String type;

protectedint typeID;

protected String priority;

protectedint priorityID;

protected String status;

protected int statusID;

protected String resolution;

protected String assignee;

protected String assigneeUsername;

protected String reporter;

protected String reporterUsername;

protected String created;

protected String updated;

protected String version;

protected String fixVersion;

protected String component;

protected String due;

protected String customfields;

Step 4: If you have your own Item class, make sure the properties are set in the RSSDigester

protected void addItemProperties(RSSDigester rssDigester)

{

rssDigester.setItemClass(EclipseJIRAConstants.ISSUE_ITEM);

rssDigester.addBeanPropertySetter("rss/channel/item/key","key");

rssDigester.addSetProperties("rss/channel/item/key",
"id", "keyID");

rssDigester.addBeanPropertySetter("rss/channel/item/environment",
"environment");

rssDigester.addBeanPropertySetter("rss/channel/item/summary",
"summary");

rssDigester.addBeanPropertySetter("rss/channel/item/type",
"type");

rssDigester.addSetProperties("rss/channel/item/type",
"id", "typeID");

rssDigester.addBeanPropertySetter("rss/channel/item/priority",
"priority");

rssDigester.addSetProperties("rss/channel/item/priority",
"id", "priorityID");

rssDigester.addBeanPropertySetter("rss/channel/item/status",
"status");

rssDigester.addSetProperties("rss/channel/item/status",
"id", "statusID");

rssDigester.addBeanPropertySetter("rss/channel/item/resolution",
"resolution");

rssDigester.addBeanPropertySetter("rss/channel/item/assignee",
"assignee");

rssDigester.addSetProperties("rss/channel/item/assignee",
"username", "assigneeUsername");

rssDigester.addBeanPropertySetter("rss/channel/item/reporter",
"reporter");

rssDigester.addSetProperties("rss/channel/item/reporter",
"username", "reporterUsername");

rssDigester.addBeanPropertySetter("rss/channel/item/created&quot,
"created");

rssDigester.addBeanPropertySetter("rss/channel/item/updated",
"updated");

rssDigester.addBeanPropertySetter("rss/channel/item/version",
"version");

rssDigester.addBeanPropertySetter("rss/channel/item/fixVersion",
"fixVersion");

rssDigester.addBeanPropertySetter("rss/channel/item/component",
"component");

rssDigester.addBeanPropertySetter("rss/channel/item/due",
"due");

rssDigester.addB../../eanPropertySetter("rss/channel/item/customfields",
"customfields");
